的主要特征之一 vMix 27 are Zoom 集成,使 远程生产商 to bring in (theoretically) an unlimited number of remote guests, vMix Senior Systems Engineer Heath Barker 在采访中报道 流媒体特约编辑肖恩·林 of SLVLive 在vMix展台 NAB 2024. Barker还快速演示了该功能的工作原理.
Shawn Lam: 我和vMix的希斯·巴克在NAB 2024, 我们将讨论vMix的最新版本, which is vMix 27. 快速概述一下27的一些重要特性?
Heath Barker: vMix 27最大的特点是我们的Zoom集成. So it's possible to take all of our Zoom callers from a meeting directly into vMix as individual inputs. So that means that you can bring in both their video and their audio independently so that you can do things like ISO record them or stitch them all together into a full layout with having your main caller and then various panelists on the side or something like that. Zoom有很大的灵活性. 另一件很酷的事情是历史上我们有vMix Call, 只有8个来电者. Zoom在输入数量方面没有限制. 限制在于带宽——所以你有30兆的带宽可以使用, 这相当于5个高清1080P源. 如果你有一个高级Zoom账户, 你就可以使用1080P了, 但也可能是2360P, 如果你把它们作为小的个体输入, 看起来会很棒. 这是主要的一个.
Shawn Lam: 这与桌面捕获有什么不同?
Heath Barker: 在桌面捕获, 你一次只能带一个进来, 而现在你可以把他们都带进来. And it was difficult to do things like bring in individual inputs and their individual audio so that you could do things like editing afterwards or recording ISO recording of each. 比这好多了. 这一切都在vMix中运行，所以你不需要第二个显示器来录制.
Shawn Lam: For me, 当我看或者使用这个功能的时候, 干净的输入是非常重要的, 因为当你使用桌面捕捉引入缩放输入时, 你总是能得到他们的名字和他们的连接带宽. 里面总是有事情发生.
非常干净，非常棒. 然后你可以把你的覆盖层，比如你的下三分之一和其他的东西放在它们上面. 我们有一个演示，稍后可以给你们看.
所以你不仅可以把独立的变焦输入作为ISO相机或ISO参与者, 我们也可以发送回去. 这是怎么做到的呢?
Heath Barker: vMix可以访问四个输出. You can just select one and whatever you're sending on that output will be what your Zoom participants see as you in the meeting, 如果这说得通的话.
Shawn Lam: So that could be a program, but it could also be any other output that you designate as an output?
Heath Barker: Correct. 如果你有主人的话, 你可以直接给他们发送视频，因为这对他们来说更自然, 但如果极速的参与者真的想看看整个节目是什么样子的, 你可以把整个节目和它的样子发给他们. 这包括他们和所有的东西, 这样他们就能完全了解发生了什么, 比如直播之类的.
Shawn Lam: 传统上，当你做的时候 mix minus with video, 你把视频发给他们，然后再发给他们, 这就是我们在说的吗. 我们可以选择送回什么. 这可能会让观众感到困惑，但更糟糕的是音频的混合. 我们不想给他们传回音频. 那么你是怎么做到的呢?
Heath Barker: 所以vMix本身会为你混合负. I recognizes a Zoom input, and if it's a Zoom input, it means the participant could be talking. 所以我们永远不会把它送回去. 我们把它减去. 它是负的, hence mix minus, 所以我们发回的就是你想要发送的所有内容减去Zoom输入.
Shawn Lam: 没有回音，没有尖叫声，回音，没有反馈. Just happiness.
Heath Barker: 现在你仍然可以得到一些回音或者类似的东西，如果你的参与者, for instance, were not wearing headphones and had very loud speakers and they were getting noise back into their microphones. 所以这样的事情仍然可能发生. 你肯定想要，vMix总是说，测试，测试，再测试. 但就mix minus而言，它在vMix中非常可靠. 所以我所做的是建立一个关于Zoom集成如何工作的小演示. 在这里，我在手机上设置了Zoom. 所以我以Zoom呼叫者的身份呼叫vMix. 这是我，这是我从vMix得到的缩放反馈. 现在我可以把它放到我事先准备好的镜头里, 比如这个有一堆图层给我所有的Zoom参与者, these guys here, 其中一个就是我. 我把拇指从相机上拿开对准自己，然后直接切到那个. 所以我可以变成我自己，试着控制我自己. There we go. 然后切换到另一个镜头，切换到另一个镜头，切换到我自己. 所以，这是一种更漂亮的变焦能力, something that's really customized for what look you are looking for rather than what Zoom wants.
Shawn Lam: 添加Zoom输入有多容易? 你能给我们讲讲吗?
Heath Barker: Sure. So it's a matter of going to Add Input in the bottom corner and then selecting Zoom as your input, clicking OK, 寻找新的输入. 在缩放管理器中，你可以从参与者列表中选择. 当参与者出现在Zoom会议上, 你可以右键点击它们，你可以选择添加它们作为一个新的输入, 或者你可以将它们添加为现有的缩放输入，如果你已经在那里建立了一个. 所以在vMix中添加人非常非常简单.
Shawn Lam: 然后一旦你添加了，比如说1 2 3或4个输入，切换有多容易? 谁负责输入?
Heath Barker: 如果你看这里的缩放输入, 我可以右键点击这里，把我的参与者改成我想要的人. 你可以在这里进行转换. 这非常非常简单.
Shawn Lam: Excellent. 好的，非常感谢你，希斯. 这是在NAB 2024上对vMix 27的观察.
